Spesolimab 450mg/7.5ml solution for infusion vials

BackgroundPyoderma gangrenosum (PG) is a rare disease causing painful skin ulcers, typically starting with tender pustules that quickly develop into painful ulcers. Traditional treatments like glucocorticoids and immunosuppressants often have adverse effects and limited efficacy, making them unsuitable for all patients. Recent evidence shows that biological agents are more effective and safer, leading to increased acceptance. However, selecting the most suitable biological agent from the many available options remains a significant challenge for both physicians and patients.ObjectiveTo systematically review the treatment outcomes of two biologics: TNF (tumour necrosis factors)-α inhibitors and IL (interleukin) inhibitors in pyoderma gangrenosum.MethodsA search of Pubmed was conducted on September 7, 2024. A total of 107 studies were included using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.ResultsA total of 139 patients were included. Ninety-two were treated with TNF-α inhibitors and 47 with IL inhibitors. The number of included cases and the efficacy are Infliximab (n=52, 88.4%), Adalimumab (n=23, 91.3%), Etanercept (n=13, 84.6%), Certolizumab (n=3, 66.6%), Golimumab (n=1, 100.0%), Anakinra (n=11, 100.0%), Canakinumab (n=7, 100.0%), Secukinumab (n=5, 40.0%), Brodalumab (n=3, 100.0%), Ixekizumab (n=1, 100.0%), Ustekinumab (n=12, 100.0%), Spesolimab (n=3, 100.0%), Guselkumab (n=2, 100.0%), Tildrakizumab (n=2, 100.0%), Risankizuma (n=1, 100.0%). Among them, 46.0% (n=64) achieved complete remission, including 47 (33.8%) who used TNF-α inhibitors and 17 (12.2%) with IL inhibitors. And the total effective rate of IL- inhibitors (93.6%) was higher than that of TNF-α inhibitors (88.0%), but had no statistical significance (p>0.05). However, it takes less time for IL inhibitors to reach partial remission or complete remission. Additionally, in infliximab group, the number of adverse events that occurred was large and varied.ConclusionDifference in effective rate shows no statistical significance between two kinds of agents. However, IL inhibitors demonstrate an advantage with shorter treatment cycles. Additionally, Infliximab has a wider range of side effects and should be used with caution.PROSPERO number: CRD42024608039.

Abstract Background Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a considerable disease burden. Existing treatment options are limited and often suboptimal; a high unmet need exists for effective targeted therapies. Objectives To explore the effects of spesolimab treatment in patients with HS. Methods This randomized double-blind placebo-controlled proof-of-clinical-concept (PoCC) study was conducted at 25 centres across 12 countries from 3 May 2021 to 21 April 2022. Patients had moderate-to-severe HS for ≥ 1 year before enrolment. Patients were randomized (2 : 1) to receive a loading dose of 3600-mg intravenous spesolimab (1200 mg at weeks 0, 1 and 2) or matching placebo, followed by maintenance with either 1200-mg subcutaneous spesolimab every 2 weeks from weeks 4 to 10 or matching placebo. The primary endpoint was the percentage change from baseline in total abscess and inflammatory nodule (AN) count at week 12. Secondary endpoints were the absolute change from baseline in the International Hidradenitis Suppurativa Severity Score System (IHS4), percentage change from baseline in draining tunnel (dT) count, the proportion of patients achieving a dT count of 0, absolute change from baseline in the revised Hidradenitis Suppurativa Area and Severity Index (HASI-R), the proportion of patients achieving Hidradenitis Suppurativa Clinical Response (HiSCR50), the proportion of patients with ≥ 1 flare (all at week 12) and patient-reported outcomes. Results In this completed trial, randomized patients (n = 52) received spesolimab (n = 35) or placebo (n = 17). The difference vs. placebo in least squares mean is reported. At week 12, the percentage change in total AN count was similar between treatment arms: –4.1% [95% confidence interval (CI) –31.7 to 23.4]. There was greater numerical improvement in the spesolimab arm, as measured by IHS4 (13.9, 95% CI –25.6 to –2.3); percentage change from baseline in dT count (–96.6%, 95% CI –154.5 to –38.8); and the proportion of patients achieving a dT count of 0 (18.3%, 95% CI –7.9 to 37.5). Spesolimab treatment also improved HASI-R and HiSCR50 vs. placebo. Spesolimab demonstrated a favourable safety profile, similar to that observed in trials in other diseases. Conclusions This exploratory PoCC study supports the development of spesolimab as a new therapeutic option in HS.

Introduction Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening disease characterised by recurrent flares of widespread neutrophilic aseptic skin pustular eruption. Despite the availability of approved biologics for GPP in Japan, Taiwan and Thailand, associated evidence is largely based on uncontrolled studies in which acute flares were not directly assessed. Therefore, there is a high unmet need to investigate new rapid-acting effective treatments that resolve symptoms associated with acute GPP flares. A prior Phase I proof-of-concept study showed rapid improvements in skin and pustule clearance with a single intravenous dose of spesolimab, a novel anti-interleukin-36 receptor antibody, in patients presenting with an acute GPP flare. Here, we present the design and rationale of Effisayil 1, a global, Phase II, placebo-controlled study to evaluate the efficacy, safety and tolerability of spesolimab in patients presenting with an acute GPP flare. Methods and analysis At least 51 patients with an acute GPP flare will be randomised 2:1 to receive a single 900 mg intravenous dose of spesolimab or placebo and followed for up to 28 weeks. The primary endpoint is a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 (pustule clearance) at Week 1. The key secondary endpoint is a GPPGA score of 0 or 1 (clear or almost clear) at Week 1. Safety will be assessed over the study duration by the occurrence of treatment-emergent adverse events. Blood and skin biopsies will be collected to assess biomarkers. Superiority of spesolimab over placebo in the proportion of patients achieving the primary and key secondary endpoints will be evaluated. Ethics and dissemination The study complies with the ethical principles of the Declaration of Helsinki, the International Council for Harmonisation’s Good Clinical Practice and local regulations. Ethics committee approvals have been obtained for each centre from all participating countries and are listed in online supplementary file 1. Primary results will be published in a peer-reviewed journal. Trial registration details ClinicalTrials.gov identifier: NCT03782792 ; Pre-results.
